Okay so shen the ap tank the main point of the build is his first skill Vorpal blade the ap in the build helps this do more damage. With the Ryilai's this attack slows the enemy which is where your boots help, as you move faster then most characters now and with the low cooldown on it you can keep slowing them. Your lane partner will get most of the kills so be for warned this build is for support you wont have a lot of kills but a lot of assists. Try to watch the map and see who needs help cause of your ult, The ap in the build will give your shield that you put on your ally more hp same with your own shield he has. Try to ult to an ally that need help and taunt the enemy so that they can get away then run yourself, or if you ult to an ally and they start killing of course you help kill the enemy and get the assists. Have fun with this build i have been playing it for awhile now and have got it down. This build takes some skill to use cause you dont have a bunch of hp for a tank.
